STERILIZER.

$PEGIFICATION forming part of Letters Patent No. 785,354, dated March21, 1905.

Application filed No ember 7, 1904. Serial No. 231,691.

izer in which it is aimed to consume all of the.

gases of combustion and also to provide a simple means by which smallarticles may be thoroughly sterilized, the entire device being adaptedto be detaohably secured to an ordinary gas-fixture.

To these and other ends, which will hereinafter appear, the inventionconsists in the novel features of improvement and combination andarrangement of parts hereinafter described, and finally summarized inthe appended claims.

Reference is to be had to the accompanying drawing, forming part hereof,which illustrates a vertical central section of my improved device.

Referring to the drawing, 1 indicates a suitable drum or casing, whichhas an opening 2 in the bottom 3 thereof, the said opening being largeenough to permit of the free passage of the nipple end 5 of a gas-pipe6. When the burner 7 is screwed onto the nipple 5 as far as it will go,it will force the bottom 3 of the drum or casing 1 against the shoulder8 of the fitting, thereby securely holding said casing in place. Theburner 7 in my device is of the Bunsen pattern, whereby a great heat isobtained, the said burner being provided with the usual air-inlet 9 andwith a cap 10, provided with openings 11, from which the flame emanatesand impinges against the bottom of a reservoir 12, which is adapted tocontain water or a sterilizing fluid. The reservoir 12 is provided withacircumferential bead or ridge 12 and rests upon the casing 1 at thepoint 13 when in position. By this construction the reservoir 12 can bereadily removed and fluid changed without taking the casing from theburner. As an extra means for sterilizing and one in which smallarticles may be placed, I provide a basket 14:, the same being made ofwoven wire or perforated plates, as desired, the basket being held insuspension within the reservoir by a circumferential flange or lip letand is also provided with a hook 15, by which it may be handled and alsobe suspended from the outside upon the top edge of reservoir 12. A capor cover 16 is provided in which there is an opening 17, through whichopening excessive steam may escape. If the basket 14 is not intended tobe used, it may be removed and the articles hung or placed directly inthe reservoir proper.

In the casing 1 there is an opening 18, through which the burner can beseen for the purpose of ignition and regulation. I

also provide air-inlets 19 at or near the bottom of the casing andoutlets 20 at the upper portion thereof, as shown. The space 21 betweenthe casing 1 and reservoir 12 permits of a free circulation of heatedair around the reservoir, the openings 19 atthe bottom of the casingadmitting the air and the openings 20 at the top letting out the gasesof combustion, whereby a circulation of hot air is created around thesides as well as at the bottom of the reservoir 12, containing thesterilizing fluid. The casing confines the hot air and prevents theflame from being extinguished by gusts of air. The top edge 22 of thereservoir 12 1 is turned inwardly, as shown, to prevent the boiling overof the liquid.

I do not wish to limit myself to the precise details of constructionshown and described, as the same may be varied in many particularswithout departing from the spirit of my invention, and it will of coursebe understood that wherever in the foregoing specification and appendedclaims I speak of a gas-pipe any gas fixture, bracket, or the like isintended to be covered thereby.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. A sterilizer adapted to be attached to a gas-pipe, comprising acasing, the same being provided in its bottom with an opening adapted topermit of the passage of the nipple end of the gas-pipe, a burneradapted to be screwed onto said nipple end and to securely hold thecasing in place, and a fluid-receptacle suspended Within said casing andadapted to receive the flame from said burner for heating the fluidtherein.

2. A sterilizer adapted to be attached to the nipple end of a gas-pipe,comprising a casing, the same being provided with an opening in itsbottom adapted to permit of the free passage of the said nipple end, aBunsen burner adapted to be screwed onto the nipple end of saidgas-pipe, the said burner being adapted to securely hold said casing inposition, and a fluid-chamber Within said casing adapted to receive theheat from said burner, and a detachable secondary receptacle within saidfluid-chamber, substantially as described.

3. A device of the character described, comprising a casing havingair-inlet openings at HORACE N. FOWLER.
